To > get around this, add the following line to /etc/sysctl.conf: > > kern.timecounter.hardware=i8254 Added above line to /etc/sysctl.conf $ cat /etc/sysctl.conf vfs.usermount=1 kern.timecounter.hardware=i8254 Now only 2 lines in this file. I have adjusted the clock thereafter and will check it again later > There are multiple pieces of hardware capable of supplying timing > information to the OS.
